Radiation Therapy Services Closes $100 Million Debt Financing

FORT MYERS, Fla., Dec. 16 /PRNewswire-FirstCall/ -- Radiation Therapy Services, Inc. , a leading operator of radiation therapy centers, announced today it closed its previously announced $100 million debt financing. The Company has added a $50 million accordion feature to the facility, which allows it to increase the aggregate principal amount of the Term B financing to $150 million, at the Company’s option.

The $100 million Term B loan has an initial interest rate spread of 200 basis points, with the opportunity to permanently reduce the spread to 175 basis points after six months, provided the Company’s leverage ratio is below 2:1.

The Company used the proceeds of the Term B loan to pay off its pre-existing Term A loan as well as the borrowings drawn on its $140 million revolving credit facility. The current availability under the revolving credit facility is $140 million.

The Term B loan is a seven-year borrowing with a maturity of December 31, 2012. The maturity for the revolving credit facility remains March 15, 2010. Participants in the Term B financing include institutional investors as well as the Company’s senior bank lending group.

David M. Koeninger, Executive Vice President and Chief Financial Officer, stated, “We are extremely pleased with the high level of interest received among institutional investors, particularly institutions new to Radiation Therapy. This additional capital source will support program expansions within our existing local markets, entry into new local markets and ensure that we have the most advanced treatment technology. We look forward to a healthy, long-term relationship with our new investors.”

The Company will be reporting the closing of this credit facility on a Form 8-K filed with the SEC on or before December 22, 2005.
